Description

Technical Field

[0001] This utility model relates to the field of copper powder preparation technology, and in particular to a centrifugal solid-liquid separation device for copper powder suspension preparation. Background Technology

[0002] In the production of electrolytic copper powder, a small amount of fine powder will be discharged with the washing water during the washing process. If the filter cloth is damaged during the washing process, the electrolytic copper powder will also be lost with the washing water. Electrolytic copper powder is mainly recovered by measures such as wastewater pressure filtration, precision filtration, and sedimentation in sedimentation tanks, but the recovery efficiency is poor.

[0003] The patent document with announcement number CN212856884U proposes a solid-liquid separation device for copper powder production. However, the above patent only has the effect of spraying the inner wall of the filter cylinder, which cannot effectively clean the filter cylinder and is prone to clogging. This makes it difficult to effectively separate the solid and liquid of the copper powder suspension. Therefore, we propose a centrifugal solid-liquid separation device for copper powder preparation to solve the above problems. Utility Model Content
